• The extent, condition, use, and performance of the physical transportation network and infrastructure;
• Safety information including accidents, crashes, fatalities, and injuries for each transportation mode and for hazardous materials movement;
• Transportation’s impact on the economy, including gross domestic product, employment by industry and occupation, and transportation-related consumer and Government expenditures; and
• Transportation’s impact on energy use.

This month, the following tables received new data:

• Age and Availability of Amtrak Locomotive and Car Fleets (1-33)
• Amtrak On-Time Performance Trends and Hours of Delay by Cause (1-73)
• U.S. Consumption of Energy from Primary Sources by Sector (4-2, 4-2M)
